[SPARK-1655][MLLIB] Add option for distributed naive bayes model.
Adds an option to store a naive bayes model distributively. The default
behavior, in which the whole model is stored on the driver node, remains
unchanged. NaiveBayes.trainâs new distMode parameter can be used to request
that a model be distributed.
When distributed, the model is stored as an RDD of model blocks. Each block
contains the labels and prior and conditional probabilities for a set of label
classes, allowing fast computation of the maximum a posteriori prediction for
each block and straightforward aggregation of these MAP predictions across
blocks.
